A question about the Monero wallet: doesn't it rotatte the addresses, like HD wallets? I'm asking this because in Bitcoin this practice is strongly discouraged, not just for privacy reasons, but for security reasons. In Monero I think the reuse address shouldn't be a issue for privacy, but what about security?

Bitcoin does not, at a low level, have any concept of addresses, only individual coins. Address reuse, at this layer, requires producing multiple digital signatures when you spend bitcoins. Multiple situations have been found where more than one digital signature can be used to calculate the private key needed to spend bitcoins. Even if you spend all the bitcoins claimed by this private key at once, it is still possible to double-spend them in theft before they confirm. While the known situations for finding the private key from signatures have been fixed, it is not prudent to assume there aren't more such situations yet unknown.

In the case of spending all the TXOs in a single transaction, there is an additional risk if someone is actively monitoring the network for vulnerable transactions: upon receiving such a transaction, they can split up their double spends such that there is only one ECDSA verification per transaction (making a single transaction for each TXO); this will cause the attacker's transactions to relay across the rest of the nodes faster than the legitimate one, increasing success of a double spend.

You only have one address in Monero. Since outputs use dual-key stealth addresses there's really no need to have multiple addresses in a single wallet:)

You rock.

Thanks for clarifying.

To clarify a tiny bit more for those who may not be familiar with how stealth addresses work, on the blockchain the addresses are never reused. The cryptography creates a new address every time automatically (just like you are supposed to do with Bitcoin, but hardly anyone actually does).

"impossible to counterfeit" should be a major selling point of cryptocurrencies. Not sure why this isn't advertised more.

A large part of taking credit instead of cash is because it's tough to counterfeit the value, yet identity theft/cc theft is still a reality.

I actually have a slogan idea that says "Monero: better than cash", since it provides all the advantages of cash (except independance over electricity and internet, granted) plus completely unforgeable, as you said (barring 51% attack, of course) and low friction (since it is electronic).

I see one use of multiple addresses: when you don't want to know that two transactions go to the same address (like if you don't want people to find you by googling your address which is on bitcointalk signature of profile, or openalias, for instance).But since there is no much of these needs, you may as well just use a second wallet.

Welp, your in the monero thread, so you're going to get a biased opinion here!

If you don't want to do the research and want the quick 'n dirty, Monero has stealth addresses and privacy (through ring signatures) baked in to the source code (cryptonote), whereas DarkCoin is more or less a conventional blockchain with required coin mixing performed at the infrastructure level.

So, in monero, the entire network is involved in the process of making things private and anonymous. Every active node is doing it. In darkcoin, there is a subset of the network (masternodes) that are responsible for making things private and anonymous. Fans of Monero think that this masternode concept is a weakness. Fans of Darkcoin don't.

When is monero 100% ready? It depends on your definition of 100% ready. If you wanted to get some monero and send it to someone else with a monero account, then its 100% ready.

If you want to do send monero to to someone else with a monero account and want to do it without touching a linux terminal, its 100% ready (www.mymonero.com)

If you want to do send monero to to someone else with a monero account and want to do it without touching a linux terminal and do it all on your computer, its ready (there are GUIs available)

I have about 5k Dollar to invest. Should i invest in Monero or Darkcoin? Can Monero make me rich?

Fixed.

It seems a lot of people are here just to get rich quickly. OK, I can't speak against this practice, I'd like to be rich too (tomorrow would be a great day for me to getting rich ).

But in cryptocoins, I think you buy some of a specific cryptocoin because you like it, and you'd like to use to pay someone for something in the future or to tip someone without compromising your privacy, in the case of Monero.

Just an observation: according to CoinMarketCap, the Monero volume was about 13000 USD in the last 24 hours. Buying 5000 USD in Moneroj at one-time has a great potential to push up the prices (and maybe a little crash later).

Yeah, after all, creating a new address is very easy. In my case I was just worried about the possibility of a hacker recovering the private key in the case of a reusing address, because there are some claims about this possibility in Bitcoin and its direct derivatives (see the second link of my first post).

I promise you that 50% of the people in this thread that will answer your question, have the correct answer, and 50% of the people in this thread that will answer your question, will not have the correct answer. You should speculate based on that

Thx this is a very good reply for me.

I have a House, a car, a good job a wife and 2 children. I think i am rich!!

But i need for my 2 childrens in 15 years about a house, no 2 House---2children

Sophia was one of the embedded databases we initially considered, but ultimately went for LMDB because it is better suited to our workloads (based on casual observation, it was impossible to test that theory at that stage;)

Ultimately we aren't preventing anyone from writing an additional implementation and submitting a PR, and we will at the very least have a BerkleyDB fall-back implementation for environments that don't play well with large MMAPs.

It doesn't matter if your address is known, as it's impossible (with our current cryptography) to analyse the blockchain and find transactions you were involved in. Even if that was possible it still wouldn't be disastrous, as all that can be observed are transactions you *may or may not* have been involved in (thanks to ring signatures). The only time multiple wallets are necessary are for separating your personal and business accounts, for instance, or for a company that wants each department to have its own address and accounts.
